Hi, Tracy....yes....just guessing about the amount of
throttle. The MicroTech handset indicated 4500 RPM. That is as high as I
dared to go without a prop on the engine. It does not take much
throttle....still plenty of throttle throw remaining. There's no doubt I
could advance the throttle more and over-rev it within a second or
two.....that's why I v-e-r-y s-l-o-w-l-y inched the throttle lever
forward ever so carefully. I did not yet look at the manifold pressure,
unfortunately....I was too busy looking for leaks, etc. None found.
Thanks for your input, Tracy. Paul Conner

Hi,
Rusty....I do not have a prop installed, as it would blow everything out
of the garage. I have had the engine up to around 4500 rpm at around
1/3 to 1/2 throttle, but that's without the load from a prop. I am hoping
to get the airplane to the airport in the next week or two and install the
prop, then see what kind of run-up rpm's I get. I talked to the guy
who sells the new Mistral rotary engine, and he said that my intake is
very similar to what they were using. They are presently changing it
to relocate the injectors very close to the intake of the engine, however
it will still have the wrap-around intake like we have with the
throttlebody on the cold side of the engine. I have a picture that
he sent to me if you are interested. Paul Conner
Paul, I hope you are only
just guessing that the engine was at 1/3 - 1/2 throttle at 4500 rpm &
no load. If running well, the engine should just about destroy
itself at > 10,000 rpm with no load. Did you happen to notice the
manifold pressure? I'd guess that it would be at about the same as
idle (12 - 13 " Hg) with no load.
